sim900 AT+CENG missing information

[alzomor]

Hi

I’d like to ask about some CENG at command.
1. Always I get the TA as 255, as I understand the value of TA ranges from 0 to 63, so what dose the 255 value means for TA?
2. I need more information about
a. <rxl > receive quality  what is the measuring unit?
b. <rxq> recive quality  what is the measuring unit?
c. <rla> receive level access minimum what is meant by “receive level access minimum” and what is the measuring unit?
d. <txp> transmit Power maximum CCCH  what is meant by “transmit Power maximum CCCH” and what is the measuring unit?


Best Regards

The measured signal level shall be mapped to an RXLEV value between 0 and 63, as follows:
RXLEV 0 = less than -110 dBm.
RXLEV 1 = -110 dBm to -109 dBm.
RXLEV 2 = -109 dBm to -108 dBm.
:
:
RXLEV 62 = -49 dBm to -48 dBm.
RXLEV 63 = greater than -48 dBm.
